Thanks for the report. I looks like you have an older card that's supported by drm2 in the kernel but not drm-stable-kmod. However, good news! We just enabled older devices in the drm-stable-kmod branch. You can try build from source here https://github.com/FreeBSDDesktop/kms-drm/tree/drm-v4.9 Or wait a week or so until we have updated the drm-stable-kmod to use the new version. (drm-next-kmod will not be updated for this since it will soon be replaced with a new version) > > > rgds > > > > Andr=C3=A1s Krasznai > > > > > > *From:* Johannes Lundberg [mailto:johalun0@gmail.com] > *Sent:* Thursday, May 24, 2018 1:14 PM > *To:* M&S - Krasznai Andr=C3=A1s > *Cc:* x11-list freebsd > *Subject:* Re: i915kms on Lenovo T510 > > > > > > On Thu, May 24, 2018 at 12:10 PM M&S - Krasznai Andr=C3=A1s < > Krasznai.Andras@mands.hu> wrote: > > Hi > > > > explicitly specifying the path for the modules did not help. > > > > Hans Peter Selansky looked at the Fatal trap and suggested to compile a > GENERIC kernel with debugging support so we can see the backtrace, I am > now compiling.
